I presume that's Graham O'Callaghan's In This Heart, released by Dragon Records.

According to this thread: Graham O'Callaghan - Where is he now?, in 2010 at least, he was living in France, but Malcolm Storey said he would pass on CD requests. There's an email for Malcolm in that thread (if it's still current).

Alternatively, it was issued by Dragon Records, so John Heydon might know where you might get one.
